Systems and methods for estimating a leak flow in a breathing assistance system including a ventilation device connected to a patient are provided. Data of a flow waveform indicating the flow of gas between the ventilation device and the patient is accessed. A specific portion of the flow waveform is identified, and a linear regression of the identified portion of the flow waveform is performed to determine an estimated leak flow in the breathing assistance system.

Leak determination in a breathing assistance system

A method for managing pressure in a breathing assistance system configured to provide breathing assistance to a patient via a patient connection system is provided. The method may include receiving one or more first pressure sensor signals from a first pressure sensor, and analyzing the one or more first pressure sensor signals. Based at least on the analysis of the one or more first pressure sensor signals, either the first pressure sensor or the second pressure sensor may be selected for use in controlling the breathing assistance provided to the patient, and the breathing assistance provided to the patient may be controlled based at least on signals from the selected pressure sensor.

Breathing assistance system with multiple pressure sensors

A method for providing battery security in a breathing assistance system configured to provide breathing assistance to a patient is provided. A battery security system of the breathing assistance system receives battery data from a battery received in the breathing assistance system, and analyzes the received battery data to determine whether the battery is approved for use in the breathing assistance system. If the battery is determined to be approved for use in the breathing assistance system, the battery is allowed to provide power to the breathing assistance system. If the battery is not determined to be approved for use in the breathing assistance system, the battery is prevented from providing power to the breathing assistance system.

Battery management for a breathing assistance system

A system for managing a supplemental gas supply in a breathing assistance system configured to provide breathing assistance to a patient includes a temperature sensor and a control system. The temperature sensor is configured to measure a temperature associated with a breathing assistance system configured to deliver a first gas and a supplemental gas toward a patient. The control system is configured to automatically control the flow of the supplemental gas based at least on the monitored temperature.

Supplemental gas safety system for a breathing assistance system

A system for wireless data communication for use with a breathing assistance system configured to provide breathing assistance to a patient is provided. The system includes a wireless notification module, one or more wireless repeaters located remote from ventilation system, and a wireless receiver located remote from the one or more wireless repeaters. The wireless notification module is coupled to a ventilation system and configured to wirelessly transmit data received from the ventilation system. The one or more wireless repeaters are configured to receive the data wirelessly transmitted by the wireless notification module, and wirelessly transmit the received data. The wireless receiver is configured to receive the data wirelessly transmitted by the one or more wireless repeaters, and communicate the received data to a user remote from the ventilation system.
